Summary:                    Zaptel doesn't detect 2100hz EC disable tone
Description: 
In an installation who has a lot of issues with faxing (mostly
communication errors), I noticed that Zaptel isn't detecting the 2100hz
tone and therefore is not disabling EC for that channel.

I expect a line like that in syslog:



Jul 16 14:23:04 pabx kernel: zaptel Disabled echo canceller because of
tone (rx) on channel 1



But I get it only very rarely. Faxes are sent and received via a telco
provided PRI. The board used is a TE110P. There is also a TE410P on the
same box but it is not used for faxing.

Unfortunately, I haven't had time to look into this anymore and I'm not
sure at the moment when I might be able to get back to it.  I haven't heard
any more reports internally of fax tone detection being a problem, but I
fear that those using fax are using a dedicated extension and disabling ec
in the dialplan as part of handling that extension.
